Re: 7 YO Behavior Issues
Has anything major changed in his life in the last six months to a year? Is he sleeping through the night? Possible night terrors? Don't take this personally I am just throwing ideas out there. The way you are describing him it sounds like someone hurt him and he is mad at you for not protecting him. If I were you I would really consider taking him in to a therapist who can then figure out what is causing this sudden change in behavior.
